Putting tools away is a piece of cake when there's plenty of space leftover in the toolbox. Just chuck 'em in there and get on with your day. But stuff likes to expand, so the toolbox tends to be full to overflowing, so the tools don't get put away, and now there are tools all over the house, and now you spend 15 minutes muttering under your breath searching for your hammer. Ain't nobody got time for that. Clearly, you need to clear things out of your toolbox. Clearing things out of your toolbox is easy when there's plenty of time leftover in your day. But commitments like to expand, so the day tends to be full to overflowing, so the toolbox doesn't get cleared, etc. You've got resources like time, money, space, and cognitive load. Stuff likes to expand and use it all up. Things are going to spill over. That's how life works. Things in general tend to be kind of a frustrating mess with not enough room to move around in. And everything's connected!
